Even on a Mac, this link:

About lossless audio in Apple Music - Apple Support

states that to listen to songs at sample rates higher than 48 kHz, you need an external digital-to-analog converter.

If you want a definitive answer, you will have to contact Apple Support.

. Why is apple withholding support from iTunes?

Anyone know if or when Apple intends to support iTunes on PC?

Check - Got that... now the OP question. Why is apple withholding support from iTunes? PC users are by far the largest population and therefore will have the most users with external DACs and other equipment capable of handling HD audio. iTunes should have been the easiest of the platforms to integrate HD audio.

Anyone know if or when Apple intends to support iTunes on PC?

"...external digital-to-analog converter." You only need an external DAC if your computer/phone/etc does not have a DAC capable of decoding above 48 Khz.
